Hillary Clinton, who was then secretary of state, says she believes the Pakistanis knew bin Laden was hiding in their country, but that the United States was unable to prove the suspicion.

“There was never any evidence that we could uncover that led directly to the top of the Pakistani military and intelligence service,” Clinton told CNN in a primetime special on the raid set to air on Monday. “I believe Pakistanis knew. I believe Pakistanis either in service or retired or both knew.”

Meanwhile, the network also tracked down Sohaib Athar, the Pakistani software engineer who unwittingly broke the news that the raid on the bin Laden compound was underway.
